Definitions

  • the invention relates to a container, essentially of rectangular cuboid shape, for tape cassettes with a raised head part, in particular for compact cassettes, with a bottom part which has at least one bottom wall and a rear wall and / or a front wall and bottom part side walls, and with a at least consisting of a cover wall cover part, which optionally has a receiving pocket with at least one pocket front wall for the tape cassette.
  • a cassette container in a case, e.g. with DE-AS 13 00 864 known.
  • the head part of the cassette is located in a pocket cover part, the clear width of which is considerably greater than the height of the head part.
  • Arresting pins are arranged on the bottom wall, which engage more or less deeply in the winding cores when the container is closed. Depending on how deep the pins engage, the cassette is either crooked or almost straight to the container bottom and lid walls, so that there is a lot of useless space in the container and the container is too high.
  • bottom and top walls of such containers are seen from the opening side of the container with a low wall thickness and the articulated connections with a larger wall thickness in order to be able to demold the parts produced by injection molding.
  • Another container of the type outlined above is known on the compact cassette market, which is characterized by an extremely thin wall thickness of the pocket front wall and the adjacent parts of the bottom wall in order to reduce the total height of the container in the region of the head elevation of the cassette.
  • the invention has for its object to provide a container of the type described with the smallest possible height with unchanged direction of insertion of the cassette into the container.
  • a container essentially of rectangular cuboid shape, for tape cassettes with an elevated head part, in particular for compact cassettes, with a bottom part which has at least one bottom wall and a rear wall and / or a front wall and bottom part side walls, and with an at least consisting of a cover wall cover part, which has a receiving pocket with at least one pocket front wall for the tape cassette, thus solved that along the transverse axes of the container, the cover wall has a decreasing wall thickness from its outer longitudinal edge in the direction of the receiving pocket.
  • the user of the container according to the invention does not have to get used to it and places the cassette head first in the container.
  • the inner surface of the pocket front wall is arranged at least parallel to the inner surface of the top wall, which has the decreasing wall thickness.
  • An angle between approximately 30 and approximately 120 angular minutes, in particular approximately 50 angular minutes, has proven to be advantageous between the inner surface and the outer surface of the cover wall.
  • the wall thickness of the cover wall can practically decrease continuously or discontinuously, in particular with a step or depression, from the outer longitudinal edge to the pocket.
  • the wall thickness of the cover wall decreases from the outer longitudinal edge in the direction of the receiving pocket in a ratio in the range between approximately 3: 1 to 1.5: 1, in particular approximately 2: 1.
  • the wall thickness of the bottom wall decreases in the same direction as the top wall.
  • the inner surface of the bottom wall can expediently also have a small angle with its outer surface. If the container is designed without a receiving pocket for the raised head part of the cassette and the bottom and lid parts are connected to one another via articulated devices, the top wall and / or the bottom wall can decrease along the transverse axes of the container from the respective outer longitudinal edge in the direction of the axis of the articulated devices exhibit. This decreasing wall thickness can expediently have the same features that were described above for the receiving pocket version.
  • closed container has a substantially cuboid-shaped receiving space for the cassette, which is inclined within the outer contour.
  • a container 5 with a compact cassette 6 accommodated therein (according to DIN 45 516) is shown in cross section and essentially consists of a base part 7 and a cover part 8.
  • the cassette 6 has a head part 9 with an increased height H compared to the height h of the rest Cassette body 10. If another tape cassette also has an elevation on one long side, which can serve a completely different purpose than the accommodation of magnetic heads on the device side, the container according to the invention is also suitable for this tape cassette.
  • the lid part is formed with a pocket 11 for receiving the head part 9 of the cassette 6.
  • the pocket 11 has the pocket front wall 12.
  • the lid part 8 comprises a lid wall 13 and the bottom part 7 a bottom wall 14. The latter is connected to the rear wall 18. Bottom part side walls are not visible due to the selected sectional view.
  • the wall thickness d decreases significantly. From the value d i to the value d 2 , the ratio decreases approximately like 2: 1. This thickness ratio should decrease in the order of magnitude in the range between approximately 3: 1 to approximately 1.5: 1. In the selected example, the thickness decreases continuously from the edge L to the longitudinal line A and then increases again slightly to the longitudinal line B. A line is thus provided in line A and the course of the decrease in thickness over the transverse axis is discontinuous.
  • the decrease angle a is approximately 50 minutes of angle in the illustration. However, it can be in the range from approximately 30 to approximately 120 angular minutes, in particular between 30 and 60 angular minutes.
  • the inner surface 15 of the lid wall 13 is arranged parallel to the inner surface 16 of the pocket front wall 12. If these surfaces 15 and 16 are arranged to diverge, the container height H 1 > H is too great in this area.
  • the inner surface part 17 of the bottom wall 14, which is adjacent to the pocket front wall 12, can also advantageously be formed lying parallel to the inner surface 15.
  • the bottom part 7 also has locking pins 20 which engage in the winding cores 21 of the cassette 6 in the cassette housing 22.
  • the position of the cassette 6 in the container 5 can depend on the shape of the locking pins 20 and the drive opening in the winding cores.
  • the inner shape of the container 5 and locking pin 20 are also suitably matched to the cassette 6 in order to obtain a very favorable low container height C.
  • a container for a tape cassette of approximately cuboid shape with a raised head part is formed with a bottom and top wall that can be moved relative to one another by means of joint devices.
  • One of said walls is designed with a removable wall thickness from its outer longitudinal edge in the direction of the joint devices.
  • the other wall can also have a wall thickness that decreases in the same direction.
  • One of the walls can also be provided with a pocket for receiving the raised head part.
  • the inner surface of the wall provided with the pocket can also be arranged at least parallel to the inner surface of the front wall of the pocket.
  • the container can advantageously be used for any cassette of the type specified above for audio, video and / or data recording, since a minimum overall height C of the container is achieved with minimal material to be used.
